Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a packaging bag suitable for packaging triangular sandwich sandwiches.

[Prior Art] Conventionally, a packaging bag 101 as shown in FIG. 5 has been known as this type of packaging bag for sandwich sandwiches.

This packaging bag 101 is formed by overlapping two large and small truncated triangular sheets using a single thin synthetic resin film so that it becomes a funnel shape when expanded. The portion 102 side is open to allow insertion of the sandwich A, and the tapered end portion 103 side is sealed.

This packaging bag 101 has a tapered edge 10 at the center of one side of the bag 101 for easy opening.
Perforation line 1 from 4 to near wide edge 105
06 is formed.

When a triangular sandwich A is packaged with this packaging bag 101, the sandwich A is packaged so that the perforation 106 is located at the center of the sloped surface of the sandwich A, as shown in FIG. When taking out the packaging bag 101, pull it on the surface of the bag 101 in the direction of the arrow while pressing it with your thumbs from both sides of the perforation line 106, tearing the bag 101 along the perforation line 106 with this pulling force, He was taking out Sanderutsch A from storage.

[The problem that the idea aims to solve]

However, in the packaging bag 101 having such a structure, when removing the stored sandwich sandwich A, it is necessary to press both sides of the perforation line 106 to open the bag.
There was a problem with the container becoming deformed and the ingredients inside protruding.

Also, the perforation line 106 allows for easy opening.
If the hole is made large, dust and insects may enter through the hole along the perforation line 106, which poses a sanitary problem.

These problems can be solved by forming the packaging bag from a uniaxially stretched film and providing a non-welded part on one side of the welded peripheral edge of the bag that can be torn in the film stretching direction. The non-welded part is formed to have the same width as the periphery of the other side of the bag and overlaps closely with each other, so when the bag is opened, the non-welded part overlaps with the periphery of the other side. Once the package gets caught on the fingertip, it takes a long time to separate the two, making opening the package difficult. For this reason, it is sufficient to make the non-welded part protrude from the other side and form the opening start protrusion, but
If only the opening initiation protrusion protrudes, there is a problem that if the protrusion gets caught on another object during handling, the package may be torn or the package may be opened unexpectedly.

Furthermore, the opening initiation protrusion formed by the non-welded part has its base end formed as a weak welded part that is integral with the welded part, and when the seal is opened, the weak welded part is torn from the other side by tearing force. The bag is opened while being separated, but when opening the bag, the protrusions may tear along the weakly welded part, making it impossible to open the bag. Even when the film can be torn, the width of the film to be torn gradually becomes smaller, making it impossible to tear the film completely to the end, making it difficult to remove the sandwich from the bag.

The present invention was created in view of these problems, and its purpose is to provide a packaging bag for sandwich sandwiches that can be packaged hygienically and also that allows the stored sandwich sandwiches to be easily and reliably removed. It provides:

[Means to solve the problem]

In order to achieve the above object, the sandwich packaging bag of the present invention includes two truncated triangular sheets 2 and 3 made of stretched synthetic resin film whose stretching direction is from the tapered end side to the wide side. By stacking these sheets 2 and 3 so as to connect their side edges and heat welding their tapered ends, a substantially flat funnel-shaped bag body 1 with the wide side open is formed, and further, the tapered ends are The tips of both sheets 2 and 3 are made to protrude by an appropriate length from the heat-welded sealing part 5 to form protrusions 6a and 6b whose overlapping surfaces are not welded, and one protrusion 6a is attached to the other. Formed into a free protruding piece that further protrudes an appropriate length from the protruding piece 6b,
It has a structure in which two parallel cutting lines 7, 7 are provided at the center in the width direction of the free protrusion part from the tip toward the sealing part 5 to form the opening start protrusion part 9. .

[Effect]

When the sandwich sandwich is stored and packaged in the sandwich packaging bag, the opening protrusion 9 is formed at the center of the protrusion 6a, so both sides of the protrusion 6a are used to pull the sandwich against other objects. It is protected against tampering and there is no risk of accidental opening. In addition, when the package is opened, one of the tips of the sheets 1 and 2 protruding from the sealing part 5 at the tapered end is made to protrude longer than the other. The unsealing operation can be easily performed by pinching the unsealing start protrusion 9.

Furthermore, even if the unsealing starting projecting piece 9 tears along the sealing part 5 or goes over the sealing part 5, the width of the torn film gradually becomes smaller and the film is torn completely to the end. If it becomes impossible to do so, the both sides of the protruding piece 6a with the opening initiation protruding piece 9 provided in the center are also formed to be separable from the other protruding piece 6b. Part 6a
Either one of the sides can be used as an opening starting protrusion, and the packaging bag can be opened reliably.

〔Example〕

To explain the embodiment of the present invention with reference to the drawings, 1.
is made of one synthetic resin film, especially OPP film, and is made of two large and small truncated triangular sheets 2 and 3.
It is a substantially flat funnel-shaped bag formed by overlapping these sheets 2 and 3 and thermally welding the inclined edges 10 and 10 on both sides and the tapered end. It is formed into a size that can be stored.

This bag 1 is formed so that the direction from the wide part 4 side to the tapered end is the stretching direction of the film, and the wide part 4 side is open, while the tapered end side is opened to the sheet 2. , 3 are thermally welded together to form a sealing portion 5.

Furthermore, from this sealing part 5, both the sheets 2 and 3
The distal ends of the protrusions are made to protrude by an appropriate length to form the overlapping surfaces of the non-welded protruding pieces 6a and 6b, respectively, and one protruding piece 6a is further extended by an appropriate length from the other protruding piece 6b. It is formed on a protruding free protrusion.

Two parallel cutting lines 7, 7 extending from the tip 8 to the sealing part 5 are provided in the center of the free protruding piece 6a to form an opening starting protruding piece 9.

The width of the sealing portion 5 is made slightly larger than the tapered end B of the triangular sandwich A so that the tapered end B of the bag 1 fits the tapered end B of the bag 1. It has been done.

In order to store and package the triangular sandwich A in the packaging bag configured as described above, the wide part 4 of the bag 1 is made to have a large opening by separating the sheets 2 and 3 from each other. Afterwards, insert the sandwich A into the bag body 1 through the opening,
Thereafter, the wide opening portion 4 may be folded along the back side of the sandwich A and fixed with adhesive tape or the like.

At this time, in the wide part 4, the end of the large sheet 2 protrudes from the end of the small sheet 3 by an appropriate width, so it is easy to separate the sheets 2 and 3 and open them wide. It is easy to do.

Next, in order to take out the sandwich A packaged as described above from the bag body 1, at the protruding pieces 6a and 6b of both sheets 2 and 3 protruding from the sealing part 5, one of the protruding pieces is further removed. When the opening starting protrusion 9 formed at the center of the protruding piece 6a is picked up with fingers, released from the other protruding piece 6b, and pulled up toward the wide part 4 side, the bag body 1 is opened to the sandwich tip. The bag 1 is torn along the slope A by the width of the opening starting protrusion 9, and can be opened.

In this case, even if the unsealing starting projecting piece 9 is torn to pieces along the sealing part 5 or even if it gets over the sealing part 5, the width of the torn film gradually becomes smaller and the film is completely torn to the end. However, in this case, one of the two sides of the protruding piece 6a adjacent to the unsealing starting protruding piece 9 will not be able to be torn. The bag 1 may be completely opened by using the bag as a holder.

[Effect of idea]

As described above, according to the sandwich packaging bag of the present invention, two truncated triangular sheets 2 and 3 made of a stretched synthetic resin film whose stretching direction is formed from the tapered end side to the wide side side are superimposed. By connecting both side edges of these sheets 2 and 3 and heat welding the tapered ends, a substantially flat funnel-shaped bag body 1 with the wide side open is formed. The tips of both sheets 2 and 3 are made to protrude by an appropriate length from the sealing part 5 by welding to form protruding pieces 6a and 6b whose overlapping surfaces are not welded, and one protruding piece 6a is connected to the other protruding piece. The sealing portion 5 is formed in a free protruding portion that further protrudes by an appropriate length from the portion 6b, and the sealing portion 5 is formed at the center portion in the width direction of the free protruding portion.
Since the opening start projecting piece 9 is formed with two parallel cutting lines 7, 7 directed toward the opening, the sandwich can be easily inserted into the bag body 1 from the opening on the wide side. In addition, in the packaged state, there is no perforation line for opening unlike conventional sandwich packaging bags, so there is no risk of dust etc. entering into the bag body 1. Of course, it is extremely hygienic, and the structure of the opening part of the sandwich packaging bag includes both sheets 2, which protrude from the sealing part 5 by heat welding of the tapered end part.
The overlapping surfaces of the protruding pieces 6a and 6b of No. 3 are formed in a non-welded manner, and one protruding piece 6a is connected to the other protruding piece 6.
b further protrudes by an appropriate length to form a free projecting piece, and two parallel cutting lines 7, 7 extending from the tip toward the sealing part 5 are provided in the center of this free projecting piece to form an opening initiation projecting piece. Since the opening protrusion 9 is formed at the center of the protrusion 6a, when the sandwich is stored and packaged in this sandwich packaging bag, the protrusion 9 is formed at the center of the protrusion 6a. It is possible to protect the piece 6a from being caught on other objects by both sides, and therefore,
There is no risk of damage or accidental opening.

Moreover, when the package is opened, the tip protruding pieces 6 of both sheets 2 and 3 protruding from the sealing part 5 at the tapered end.
In a and 6b, one of the protruding pieces 6a provided with the unsealing starting protruding piece 9 is made to protrude longer than the other protruding piece 6b, so the tip of the protruding opening starting protruding piece 9 is pinched and the other The polymerized state can be easily separated from the projecting piece 6b, and the seal can be easily opened along the two cutting lines 7, 7.

Furthermore, when opening the package by pulling the opening initiation protrusion 9, the protrusion 9 may tear along the sealing part 5 or may go over the sealing part 5. However, if the width of the film to be torn gradually becomes smaller and it becomes impossible to tear it completely to the end, as described above, the protruding piece 6a provided with the opening starting protruding piece 9 in the center. Since both sides of the protruding piece 6b are also formed to be separable from the other protruding piece 6b, either side of the protruding piece 6a can be used as an unsealing starting protruding piece, thereby opening the packaging bag. This allows for a complete opening operation.
